3. The Advantage of Unblocked Optics Dynamic Range Near sidelobes reduced by a factor >10 from conventional antennas Gain & Sensitivity The 100 meter diameter GBT performs better than a 120 meter conventional antenna Reduced Interference Characteristics of the GBT Large Collecting Area Sensitive to Low Surface Brightness Sky Coverage & Tracking (>85%) Angular Resolution Frequency Coverage Radio Quiet Zone Unblocked Aperture state-of-art receivers & detectors modern control software flexible scheduling The Green Bank Telescope

4. NRAO Mission Statement The National Radio Astronomy Observatory enables forefront research into the Universe at radio wavelengths. In partnership with the scientific community, we: ● provide world leading telescopes, instrumentation and expertise, ● train the next generation of scientists and engineers, and ● promote astronomy to foster a more scientifically literate society. Our collaborations with WVU address all of these!
